5.50 Ct. Bi Color Sapphire Crystal from Ceylon (Sri Lanka)

This listing describes a single semi transparent bi color sapphire offered by The Natural Sapphire Company. The stone weighs 5.50 carats, and presents a various shape that follows the natural lines of its rough crystal form. Measurements are 19.30 by 6.90 by 4.80 mm, giving a long and slender profile that reflects its unstandardized cutting style. The sapphire displays a bi color distribution that moves subtly along the crystal, and the overall color intensity is assessed as medium light, which preserves a delicate and natural character. The surface retains the rough crystal cut characteristics, while the polish is graded as excellent, delivering refined surfaces where facets or natural faces remain, and allowing the stone to interact with light in a softly luminous manner.

Clarity is graded as included, evaluated at eye level, and the stone shows natural internal features consistent with its rough crystal origin. These inclusions are visible to the unaided eye, and they contribute to the individuality and provenance of the specimen rather than detracting from its aesthetic. There has been no enhancement applied to this sapphire, it is presented in its natural state without heat treatment or other modification, and this unenhanced condition is a defining attribute for collectors and connoisseurs who value untreated material. The origin is Ceylon Sri Lanka, a historical source renowned for producing sapphires with a broad range of colors and natural character, and the piece reflects geological conditions associated with that region.

The rough crystal cut and the stone dimensions lend themselves to several potential uses, depending on the wearer or the lapidary approach chosen. As provided, the specimen is suitable for collectors of natural and unenhanced sapphires who appreciate crystals in their more pristine form. A lapidary may elect to preserve the rough charm and fashion the gem into a unique freeform cabochon or faceted piece, retaining some of the existing crystal faces for a more organic appearance. Alternatively, the stone can be mounted in custom jewelry that highlights its elongated silhouette, for example set vertically in a pendant where the bi color zoning can be shown along the length of the setting, or as a distinctive centerpiece where the natural polish and surface texture remain part of the design intent.

Handling and care guidelines are straightforward, and reflect the stone's natural and included condition. Clean the sapphire using warm water and a soft brush with a mild soap solution, avoiding harsh chemicals that could affect any included surface coatings if present on other stones. Ultrasonic and steam cleaning are generally not recommended for sapphires with prominent inclusions or fragile crystal features unless evaluated first by a professional gemologist. The provenance and untreated status of this sapphire are documented by The Natural Sapphire Company, and we provide transparent information on weight, dimensions, cutting style, clarity and origin to support informed decisions. This specimen offers a distinctive combination of natural form, Ceylon origin, and unenhanced authenticity, suitable for collectors, designers and those seeking a sapphire with inherent geological character.
